Fabrication-induced imperfections in photonic wire waveguides, such asroughness, stitching errors, and discontinuities, degrade theirperformance and thereby lower the yield of large-scale systems. Thisdegradation is primarily due to the high insertion losses induced byimperfections, which scale nonlinearly with the index contrast in wirewaveguides. Here we investigate the influence of discontinuities inphotonic waveguides and later show a platform that is robust tofabrication imperfections.
